Notion x Excalidraw Helper: How It Works and When to Use It

Notion x Excalidraw Helper is a free, open-source Chrome extension that lets you copy an Excalidraw drawing and paste it into Notion as an image, then later pull that same image back into Excalidraw as fully editable shapes. It is the easiest way to keep hand-drawn diagrams in Notion without juggling exported PNGs and .excalidraw backup files.

Below is how it works, how to set it up, and how it compares with Notion’s built-in Excalidraw embed. Details are accurate as of October 2026, but extensions and embed behavior change, so check the linked pages before you rely on anything here.

What the extension actually does

The project’s GitHub README describes a two-way workflow:

• Excalidraw to Notion: you select a drawing in Excalidraw and copy it with the normal copy shortcut. When you paste into Notion, it lands as an image, and that image carries the original Excalidraw scene data inside it.
• Notion to Excalidraw: you hover over the image block in Notion and click a button with the Excalidraw logo. Once the button turns into a checkmark, you open Excalidraw and paste, and the drawing comes back as editable elements rather than a flat picture.

The README frames the problem it solves plainly: without it, you either export and upload images by hand (losing editability), or back up and import .excalidraw files, which can overwrite whatever is on your current whiteboard. The helper pastes into your existing canvas instead, so you don’t need a manual backup first.

One useful detail: people who don’t have the extension just see a normal image in Notion. Teammates can read your diagrams without installing anything. Only the person editing needs it.

Who makes it

This is a community project, not an official Notion or Excalidraw product. It is published by GitHub user CuberL under the MIT license. The releases page lists v1.2.1 as the latest GitHub release. Search snippets of the Chrome Web Store listing mention v1.2.2, but I couldn’t confirm that directly, so check the store page for the current version.

How to set it up and use it

1. Open the extension’s page in the Chrome Web Store. The GitHub README links straight to it, which is the safest way to be sure you have the right one, since several similarly named Excalidraw extensions exist.
2. Click Add to Chrome and accept the prompt.
3. Open Notion in Chrome (not the desktop app) and Excalidraw at excalidraw.com in another tab.

To put a drawing into Notion:

1. In Excalidraw, select the shapes you want (or select all).
2. Copy them with Ctrl+C (Cmd+C on Mac).
3. Click into your Notion page where the diagram should go and paste. It appears as an image block.

To edit that drawing later:

1. In Notion, hover over the image block.
2. Click the Excalidraw-logo button that the extension adds.
3. Wait until the button shows a checkmark. That means the scene data is on your clipboard.
4. Switch to Excalidraw and paste. The diagram comes back editable.
5. Make your changes, then repeat the first set of steps to paste the updated version into Notion. You’ll probably want to delete the old image block.

The README also documents loading the extension unpacked from its GitHub releases, or building it from source with yarn. That’s mostly useful for developers. Most people should use the store version, which updates automatically.

The alternative: Notion’s built-in Excalidraw embed

You don’t need any extension to show Excalidraw in Notion. Notion’s embeds help page lists Excalidraw among its supported embed providers. Notion has had a /excalidraw slash command since a 2021 release, and you can also paste an Excalidraw link and choose to embed it.

The embed has some well-documented rough edges, though:

• Live collaboration links don’t sync. In issue #7097, users reported that embedded collab-room drawings didn’t update in Notion. An Excalidraw maintainer closed it in August 2024, saying the team has “no plans to enable embedding live collab links into 3rd party websites” and that “non-collab links are stored in the browser, so that won’t work.”
• Excalidraw+ is the suggested route for real embeds. The same maintainer noted that “we do support creating proper embeddable links in Excalidraw+.”
• Private Excalidraw+ embeds can get stuck at sign-in. Issue #4233 describes a sign-in prompt inside the Notion embed that hangs. Reports say this is worst in the Notion desktop app. It was still open with new reports in March 2026. A maintainer suggested in 2023 that it can work when everyone is already signed in to Excalidraw+ in the same browser, while calling that “hacky.”

Notion’s help page also notes that embeds requiring a login to an external site may not work in its desktop or mobile apps. That matches what users report in the Excalidraw issues.

Which approach should you use?

In practice:

• Use the helper if you mostly use free excalidraw.com, want diagrams that always render for every reader, and don’t mind re-pasting after edits. This suits docs, specs and meeting notes where the diagram changes now and then.
• Use the embed if your team pays for Excalidraw+ and wants one shared, always-current canvas inside Notion, and you mostly work in a browser.
• Use a plain export (PNG or SVG from Excalidraw, uploaded to Notion) if you can’t install extensions on a managed work browser. You lose the one-click round trip, but nothing breaks.

Things to keep in mind

• Keep the image intact. The editable data lives inside the pasted image. If someone replaces it with a screenshot, or re-uploads a compressed copy, assume the round trip won’t work. The README doesn’t spell out what breaks it, so test once before relying on it.
• It’s a single-developer project. The GitHub repo is small. That’s fine for a clipboard helper, but if it stops being maintained, your diagrams still exist as normal images in Notion. You just lose easy re-editing. For critical diagrams, also keep a .excalidraw file somewhere.
• Check permissions before installing. Any extension that reads pages on notion.so can see your workspace content in that tab. Review the permissions Chrome shows at install time, and follow your company’s extension policy on work machines.
